Here is my version of the bladeRF enclosure, with engraved logo.
I used two sheets of acrylic glass 181x181mm - 3mm thick.
It cost 19€ + shipping to make (laser-cutting and engraving) online.
I did mine at Formulor, but there are many other companies using the same SVG templates.

I had the case cut at http://www.powerjackmotion.com my work is right next to their office and it was convenient and they are pretty responsive on the weekdays. Final cost for fabrication was $47 not including the nylon screws and state tax if anyone was curious.
The svg file should also be usable with services at Ponoko since I fitted all of the pieces to within the boundaries for their P2 (384mm x 384mm) sized acrylic. There are a ton of laser cutting services out there compared to 5 years ago and some local hacker/maker clubs sometimes have laser cutters available for use.

I can also provide a SketchUp file of the case with 3d board if anyone wants. Just be aware that I don't have the bottom of the board in 3D so you might need to take some calipers to the bottom and measure out where the bottom components are.
